1. A pair of charged conducting plates produces a uniform field of 12,000 N/C directed to the right, between the plates. The separation of the plates is 40 mm. In the figure, an ELECTRON is projected from plate A, directly toward plate B, with an initial speed of v0 = 2.0 x 10^7 m/s. The speed of the electron as it strikes plate B is?
2. A pair of charged conducting plates produces a uniform field of 12,000 N/C, between the plates, directed from positive plate A to negative plate B The separation of the plates is 40 mm. A PROTON is projected from plate A with a slow initial speed of v0 = 0 m/s. it accelerates towards plate B. The speed of the proton as it strikes plate B is ____?
